Suspicious walls

[phlogistonq]

If you have been watching any of the live market monitors for a while, you can often see that

1. it first takes many hours to slowly eat through a moderate amount of sells, slowly approaching a huge wall.
2. Then, as we approach the wall a few HUGE buy orders occur, typically around 1k BTC or more, buying the entire wall.
3. then, a little rapid progress is made and the slow pace of increase continues.

Does anyone else think this is suspicous?
It appears to me a few people with deep pockets are buying the big walls to artificially keep the price going up.

When you buy a wall, you get all your coins without slippage. This is desirable, unless you like paying more for each additional coin you purchase.

This. It's more like someone is trying to get all BTC they can get without pushing the price upwards.

Lots of the buys/sells that happen you dont even see on the site, therefor you will notice the bigger transactions/walls more. What is more than likely happening is that multiple people are purchasing bitcoin at the same time. Lots seem to be wasting it at satoshidice...

whoever runs that site must be making BANK!
